Poly snaps that actually snap!

thingiverse

I printed the previous poly snaps and was frustrated by the friction fit joints that seemed to require ultra-precision to print successfully multiple times before giving up in frustration. They were either too tight to even go together or so loose they fell apart completely. So I used blender to add spherical nubs and sockets that give the parts some extra tolerance and a satisfying snap when you get them together correctly. It isn't a perfect solution, but I think it helps improve the design significantly. Also, I noticed that the original poly snaps were limited to a 90-degree angle. This updated version can do a full 270-degree folding completely flat on one side without any issues. Without this addition, the red/green/blue piece in the picture would have been impossible to print successfully. I made these primarily for a coworker of mine who was impressed by my ingenuity. One of the neat things he noticed is that you don't actually need the squares, pentagons, or hexagons as these can actually be made from the triangles! See the green and white sphere - it's a clever design. I was able to print over 700 of these for just under $10 in material costs. In a batch of 52 prints, I had between 1-3 lift off the build plate, ruining them, but still managed around 50 successful prints out of the total 15 attempts! Enjoy printing! By the way, I've added two more versions with more space between the teeth to snap together easier - print two of each type and see which works best for you.
